To organise a family pool bag, pack one complete dry-change set per child, keep shared essentials in one easy-to-reach section, and leave a separate wet bag empty for the trip home. Sorting by child before you leave is usually more useful than placing every top, towel and pair of swimmers in separate piles.
The three-zone rule: one zone for each child’s clean change, one for shared items, and one for used gear. A bag with no internal divider cannot hold wet swimmers and clean clothes separately at the same time.
Give each child a ready-to-use change pack
Bundle a top, bottoms, underwear or everyday nappy where needed, and socks together. Put each complete set in a clearly identifiable pouch or section. Use a name label as well as a familiar colour or print so another adult can find the right child’s clothes without opening everything.
For a baby or toddler who still needs a swim nappy, pack the correctly fitted nappy and a clean spare with their swimming kit. Check your venue’s nappy policy before attending. Our first swimming lesson checklist covers the baby-specific items; this system focuses on keeping several people’s gear organised.
A practical two-child bag layout
| Zone | Example contents | Where to put it |
|---|---|---|
| Baby or toddler | Clean outfit, everyday nappy, spare swim nappy | Individual dry pouch above the wet zone |
| Older child | Complete dry outfit, underwear and socks | Second named dry pouch |
| Shared essentials | Entry items, hats, drinking water and any requested pool equipment | Accessible pocket or separate section |
| After-swim items | One towel per person | Near the top, without burying the dry changes |
| Wet return zone | Empty wet bag or bags | Easy to reach before anyone starts changing |
The example is a layout, not a promise that one bag fits every family. Test your actual towels and clothes at home. If the zip needs forcing, leave bulky towels outside the wet bag and use the bag for smaller wrung-out items.
Choose wet-bag capacity around the load
A small 25 × 20 cm wet bag suits compact items such as one swim nappy or baby swimmers. A large 40 × 30 cm bag gives more room for swimmers and small towels. For two children with bulky towels, two separate wet loads may work better than one overfilled bag.
The Blue Whale wet bag was available in both sizes at $15 small and $17 large when checked on 15 October 2026. Browse SJC wet bags and use the swimming wet-bag size guide to check capacity against your gear.
Pack and unpack in the order you need things
- Before leaving, place each child’s complete change in its own clean zone and leave the wet bag empty.
- At the change area, set out the next towel and dry outfit before opening the wet return bag. Keep children with the supervising adult while another adult handles gear where possible.
- Wring excess water from swimwear before placing it in the wet bag. Keep food, drinks and valuables outside the used-gear zone.
- At home, empty the wet bag promptly. Rinse the swim nappy, wash according to each label and dry everything before repacking.
SJC wet bags are leak resistant for damp gear in transit, not submersible dry bags or containers for free-standing water. Use dedicated protection for electronics. The wet bag versus dry bag guide explains the difference.
Use a final headcount for the bag
- Count complete dry outfits, not loose pieces: one set for each child.
- Count towels and check the spare swim nappy is still the right size.
- Check that the wet bag is empty and dry before it goes back into the kit.
- After the outing, replace only what was used and check for missing lids, goggles and socks.
If you are starting from scratch, matching swim bundles group a standard 4.5–12 kg swim nappy, hooded towel and large wet bag. They cover one little swimmer’s core kit, not a whole family’s capacity. Confirm fit and current inclusions before ordering.
